A method for gustatory stimulus delivery in awake rhesus monkeys.
A novel taste stimulus delivery technique along with a simple electronic onset marking system, designed for complex, neurophysiological-behavioral experiments in awake monkeys, are described. Intraoral implantation of a polyethylene tubing fistula enabled us to perform repeated, well-standardized application of various taste solutions to broad areas of gustatory receptors on the tongue, palate, pharynx and epiglottis while activity of single neurons was extracellularly recorded in behaving rhesus monkeys. By introducing an electronic marking onset and duration of the stimulation could be determined.
